I report the spectroscopic classification of PNV J06302516-6955014. Its optical spectrum was obtained on 2025-06-06.705 UT by the SpUpNIC (Crause et al, 2016) mounted on the 1.9m telescope at the Sutherland Observatory, South African Astronomical Observatory, using the grating 6 (wavelength coverage 4400-7000Å, resolution R~3000).
As reported to CBAT, PNV J06302516-6955014 was originally discovered by the Brazilian Transient Search on 2025-06-05.8825 UT at 11.2 mag (unfiltered). There is no counterpart in archival photometric surveys.
My normalized spectrum shows the Balmer and He I lines with a P Cygni profile.
The absorption minimum of this P Cygni profile in Hα is located around -600 km/s.
Combining these spectral features and its large eruption amplitude, I conclude that this object is a classical nova.
